Eighth Circuit Holds that AKS Violations Do Not “Taint” All Claims
The Eighth Circuit Court of Appeals recently issued a notable decision that offers defendants in FCA cases premised on violations of the Anti-Kickback Statute (“AKS”) significant new defenses relating to causation. The panel soundly rejected the government’s position that as a result of the 2010 amendments to the AKS, any claim provided in violation of the AKS is tainted, and therefore “false,” under the FCA. Instead, the Eighth Circuit held that for an AKS violation to render a claim false, the kickback must have been the but-for cause of the submission of the claim. United States ex rel. Cairns v. D.S. Medical LLC, No. 20-3010, 2022 WL 2930946 (8th Cir. July 26, 2022). The decision creates a circuit split with the Third Circuit and given the many courts of appeal that have not weighed in on this question, promises to generate renewed debate in district courts across the country as to the appropriate causation standard in FCA cases involving alleged violations of the AKS.
